First Claim
1. A method for controlling operation of a warewasher, said method comprising:
- detecting a condition of the warewasher that requires corrective action;
alerting a human operator of the condition that requires corrective action;
monitoring an operational parameter of the warewasher to provide an indication when the corrective action occurs;
if the corrective action does not occur, disabling subsequent operation of the warewasher; and
in response to the monitoring indicating occurrence of the corrective action, enabling operation of the warewasher.

Abstract
An apparatus reminds an operator of a need to change water in a reservoir of a warewasher. A counter that counts operating cycles of the warewasher and a sensor provides signal indicating that the reservoir has been drained and refilled. A controller responds to the counter having a first threshold value by activating an annunciator to alert the operator that is it time to change the water. Thereafter when the counter has a greater second threshold value and the controller disables operation of the warewasher until the sensor indicates that the reservoir has been drained and refilled. Thus the operator is required to change the water in order to continue using the warewasher.

12. A method for controlling operation of a warewasher that has a reservoir for water, said method comprising:
-
counting operations of the warewasher to produce a count;
sensing at least one characteristic of the warewasher that indicates draining and refilling the reservoir; and
responding to the count having a predefined value by disabling operation of the warewasher until the sensing indicates that the reservoir has been drained and refilled. - View Dependent Claims (13, 14, 15, 16, 17, 18)
